Best Paper 2007

The U.V. Helava Award, sponsored by Elsevier B.V. and Leica Geosystems GIS & Mapping, LLC is a prestigious ISPRS Award,
which was established in 1998 to encourage and stimulate submission of high quality scientific papers by individual authors or groups to the
ISPRS Journal, to promote and advertise the Journal, and to honour the outstanding contributions of Dr. Uuno V. Helava to research
and development in Photogrammetry and Remote Sensing.

The Award is presented to authors of the best paper, written in English and published exclusively in the ISPRS Journal during the fouryear
period from January of a Congress year, to December of the year prior to the next Congress. The Award consists of a monetary grant of SFr.
10,000 and a plaque. A five-member jury, comprising experts of high scientific standing, whose expertise covers the main topics
included in the scope of the Journal, evaluates the papers. For each year of the four-year evaluation period, the best paper is selected,
and among these four papers, the one to receive the U.V. Helava Award.

The third U.V. Helava Award will be presented at the 21th ISPRS Congress, Beijing, 3-11 July 2008. The fivemember jury appointed
by the ISPRS Council evaluated the 35 papers of Vol. 62 (2007) and announced its decision for the Best Paper. The winner of the 2007 Best Paper is:

The paper provides an excellent discussion of a simulation model for shared-ride trip planning. It is very interesting to read and provides
a good overview on the usage of agents for trip planning. The theory development is solid. The authors demonstrated their proposed system with
a real street network, confirming their theoretical results.

On behalf of the ISPRS and the U.V. Helava Award jury, I would like to congratulate the authors for this distinction and thank them for
their contribution. I would also like to thank the sponsors of the Award, and the jury members for their thorough evaluations.
